The upper limit of the qualification is the highest interpass temperature reached in the welding procedure test.
合格鉴定的上限为焊接工艺试验时达到的最高层间温度。
In welding process, the over range of the interpass temperature can be avoided by the control of heat treatment equipment and by the check of the far-infrared temperature instrument.
并指出焊接过程中层间温度的控制，在用热处理控制柜自动控制的同时，再采用便携式远红外测温仪对层间温度进行校核，可以避免层间温度超标现象。
The proper interpass temperature is required to prevent cold and hot cracking as well as the proper selection of welding filler material, to produce the proper creep resistance and toughness.
需要适当的程间温度和正确选择填充金属材料来防止冷热裂缝，产生适当的蠕变阻力和韧性。
